Is it possible to get the HWND of a Form?

Yes, here is a way to do it. First make sure to capture mouse / stylus input
on the form by setting the Capture property true. After that you can
P/Invoke to the Win32 API GetCapture, which returns a window handle.

this.Capture = true;
IntPtr hWnd = GetCapture();
this.Capture = false;

The following code shows you how to P/Invoke GetCapture

[DllImport("coredll")]
extern static IntPtr GetCapture();

Imports System.Runtime.InteropServices

<DllImport("coredll")> _
Private Shared Function GetCapture() As IntPtr
End Function

' Get the handle of the Form when called from inside the Form's scope.
Dim hWnd As IntPtr
Me.Capture = True
hWnd = GetCapture()
Me.Capture = False
 
Yes, very good, it is OK, thank you very much!
